Specication of Letters Patent.

Application filed November 1, 1904. Serial No. 231,013.

Patented Nov. 6, 1906.

To all whom it may con/cern Be it known that I, STEFAN HoPFEnwin SER, a subject of the Emperor of Austriaary, and a resident of Amstetten, Austr'iaungary, have invented a new and usej fulImprovementinWood-Shaping Machines and I do hereby declare the following to be an exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The invention relates to wood-shaping machines with an endless carrier for the transportation of the wooden blocks to the rotary shaping device; and the object of the invention is means whereby the wooden blocks are simply and effectively fastened to the carrier and to each other.

In the accom anying drawings, Figure 1 represents an e ovation of a wood-shaping machine constructed in accordance with my invention. .Fig 2 is a plan view, partly in section. Fig. 3 shows, on a larger scale and partly in section, the arrangement of the connecting-plates in the rotary wheel, and Fig. 4 is a cross-section through a connectingplate along the line a b of Fig. 3.

The Wood-shaping machine, which can be worked continuously, consists mainly of a wheel to which the ieces of wood are fastened, and, further, o a Shaper-head for shaping the outside surface of the block. The' Wooden blocks are held by clamps 19, which connect them with each other and also with the wheel. The wheel consists of two connected portions 15 16, which are caused to revolve slowly by worm-gearing 17,' driven by a belt. Each of the wheel-rims has on the face which is adjacent to the other an annular groove 18, in which the ends 20 of metal plates 19 are inserted in such a way that they are vertical to the periphery of the Wheel. These metal plates have pins 2l 22 projecting from both sides, which are driven into two adjacent blocks of wood upon the periphery of the wheel in such a way that the the outside.

face which has not yet been wrou ht is on By alternately attaclfliing the blocks and plates to ether in this manner the blocks become firm y secured to the wheel.

The machine also consists of a shaper head the knives of which are shaped according to the form which is to be given to the outer face. The knives are aflixed to the shaft 25 by screws 26, which can be adjusted in the longitudinal slots 27 of the shaft 25, while the slots 28 in the Vknives enable them to be adjusted radially.

To the Shaper-head With the rapidly-revolving knives the blocks of wood are carried by the slow rotation of the wheel in the direction of the arrow, when they are wrought on their outer face. During thil revolution of the wheel the blocks of wood that are wrought can be taken away, together with the insets at 29, Fig. l, and the blocks of wood to be wrought can be fixed at 30, rendering continuous running possible.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a wood-shaping machine, a wheel having two rims facing each other and formed with opposed circular grooves, in combination with lates secured in said grooves and adapte to connect the wooden blocks to be shaped with each other and with the wheel, and an ad`ustable rotary Shaper operatively arranged efore said wheel, substantially as described.

2. In a wood-shaping machine,` a Wheel with a double rim having circular opposed grooves, in combination with connectingplates lugged into said grooves and provided with pins on their adjoining faces, said pins being adapted to secure the wooden blocks to be shaped to said plates, and a rotary Shaper arranged in o erative position relatively to said wheel, su stantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

STEFAN HOPFERWIESER.
